The consequence was that the feasibility of forcing a way from the Mediterranean up into the Sea of Marmora as a purely naval undertaking came to be examined afresh in London.
This answered sufficiently well to prove the feasibility of the plan, and subsequent experiments were directed to the discovery of the best form and arrangement of the parts.
In 1862 he published a memoir, Intorno alle strie degli spettri stellari, which indicated the feasibility of a physical classification of the stars; and on the 5th of August 1864 discovered the gaseous composition of comets by submitting to prismatic analysis the light of one then visible.
This result, though widely inaccurate, came much nearer to the truth than any previously obtained; and it instructively illustrated the feasibility of concerted astronomical operations at distant parts of the earth.
2 In William Winterbotham's An Historical, Geographical, Commercial and Philosophical View of the American United States, &c. (London, 1795) there was a discussion of the feasibility of a canal between the Delaware and the Raritan.
Morse's petition for a patent was soon followed by a petition to Congress for an appropriation to defray the expense of subjecting the telegraph to actual experiment over a length sufficient to establish its feasibility and demonstrate its value.
